Re: [strongSwan] Please help - Using strongSwan to connect to CheckPoint VPN-1
Hi Andreas, Thanks again, the below was the response from our network administrator to your question: I don’t think we do any certificate based authentication. There certainly isn’t any client side certificate. Here are some more settings from our VPN:- IKE Properties:- Support key exchange encryption with: 3DES - enabled AES-256 - enabled DES - enabled Support data integrity with: MD5 - enabled SHA1 - enabled Support authentication methods: Pre-Shared Secret - disabled Public Key Signatures - disabled Advanced IKE Properties:- Support Diffie–Hellman groups for IKE (phase 1) Security associations: Group 2 (1024 bit) - enabled Reviewing the above settings I added the following line to the ipsec.conf: ike=3des-sha1-md5-modp1024 I then get the following errors: 002 test #1: initiating Main Mode 003 test #1: no IKE algorithms for this connection (check ike algorithm string) 003 test #1: empty ISAKMP SA proposal to send (no algorithms for ike selection?) Was I right to add the above setting? Just to reiterate the point again, I am using a challenge-response security token that generates a OTP (One Time Password). Just to clarify I do the following in Windows to connect to the VPN: 1) Click connect on the CheckPoint Client 2) It will prompt me for Username and Password credentials 3) I input my Username (Numeric) into the security token, upon entering the correct Username it will generate a Password 4) I then input my Username and the Password generated by the security token, it then gives a message of authenticating against a RADIUS server, then successfully connects I've never been given any certificate to install on my client. I'm optimistic that with the help of all you kind individuals that I am getting closer to connecting :-) Thanks Again, Jana --- On Thu, 4/3/10, Andreas Steffen andreas.stef...@strongswan.org wrote: From: Andreas Steffen andreas.stef...@strongswan.org Subject: Re: [strongSwan] Please help - Using strongSwan to connect to CheckPoint VPN-1 To: Sucha Singh soorma_j...@yahoo.co.uk Cc: Martin Willi mar...@strongswan.org, users@lists.strongswan.org Date: Thursday, 4 March, 2010, 6:05 Hello Jana, the log entry: ignoring informational payload, type NO_PROPOSAL_CHOSEN means that the CheckPoint box does not like your proposal.

Re: [strongSwan] Please help - Using strongSwan to connect to CheckPoint VPN-1
Hi Andreas, Thank you for your prompt response, I appreciate it. I can confirm that we are indeed using IKEv1 Main Mode. I have the pluto daemon installed, however I have no idea how to configure the ipsec.conf file. I have opened it in a text editor and I am struggling to make sense of most of the parameters. I can't appear to find anything in the online documentation to define what the parameters mean. Could you possibly construct the file for me based on the information I have already supplied? I will fill the blanks like site IP address etc. Thanks again for your time and support.

Therefore you can't use the strongSwan NetworkManager plugin to set up a connection. The CheckPoint VPN gateway most probably will use IKEv1 and XAUTH. The first thing to find out is whether IKEv1 Main Mode is used by the CheckPoint box since strongSwan does not support the potentially insecure IKEv1 Aggressive Mode. If Main Mode is possible then you can configure strongSwan's IKEv1 pluto daemon via /etc/ipsec.conf.

Re: [strongSwan] Please help - Using strongSwan to connect to CheckPoint VPN-1
Hi Jana, please go to http://wiki.strongswan.org/projects/strongswan/wiki/IKEv1Examples for IKEv1 Configuration Examples. PSK with XAUTH authentication and virtual IP addresses or RSA with XAUTH authentication and virtual IP addresse is probably the right one for you. Please refer to http://wiki.strongswan.org/projects/strongswan/wiki/IpsecConf for definitions of the individual parameters. -Daniel Sucha Singh wrote: Hi Andreas, Thank you for your prompt response, I appreciate it.
